Probléme avec un jSpinner en java

Bonjour,
bonjour,
mon code est en java il inclut l'utilisation d'un jSpinner,je travaille avec netbeans,et j'ai modifié les propriétes de model de ce jSpinner en spécifiant son min à 1 et son max à 30,je veut que lorsque j'avance ou je décrémente avec ce jSpinner,il va récupérer la variable d'un jTextField1 saisie et exécute une commande en arriére plan et envoi la réponse dans le jTextarea,or lorsque je compile et j'essaye d'avancer avec ce jSpinner j'aurai un levé d'exeption,et il ne marche plus malgré que j'ai ajouté un addChangeListener :


run:

et voici mon méthode changeListner de ce jSpinner:

Code:

private void jSpinner1StateChanged(javax.swing.event.ChangeEvent evt) {
// TODO add your handling code here:

Object sp=jSpinner1.getValue();
int i =Integer.parseInt(sp.toString() );
String target=jTextField1.getText();

try{
jSpinner1StateChanged(evt);
String cmd = "tracert -j "+i+ "" +target;
Process p = Runtime.getRuntime().exec(cmd);
InputStream in = p.getInputStream();
StringBuilder build = new StringBuilder();
Reader reader = new InputStreamReader(in);
char[] buffer = new char[512];
int nbRead = reader.read(buffer);
while(nbRead > 0) {
build.append(buffer, 0, nbRead);
nbRead = reader.read(buffer);
}
String response = build.toString();
jTextArea1.setText(response);
}catch(Exception e){
jTextArea1.append(e.toString()); }

}
